Title: Switch circuit with rush current limit function
Inventor: TAKAHATA HIROKATSU
IPC: H02M1/08
Filed: 1996-10-24
Abstract: PROBLEM TO BE SOLVED: To limit stably a rush current to the power supply control switch in an ON state of a transistor(TR) independently of a load capacity without giving effect on an output current supply capability in the case of the operation. SOLUTION: In the circuit for a power supply, a transistor(TR) 17 whose output current is limited and a TR 14 that is conductive and supplies a sufficient collector current when a difference between an input voltage and an output voltage is a prescribed voltage or below are connected in parallel. Thus, when the difference between the input voltage and the output voltage is high and a rush current might be generated, only the TR whose collector current is limited is conductive to limit the current and when the difference between the input voltage and the output voltage gets smaller, the TR with a high drive capability is conductive and a high output current supply capability is taken.

Inventor: TOMONO TSUTOMU
IPC: H01J29/07
Filed: 1986-11-26
Abstract: PURPOSE:To prevent unnecessary fluorescent screen emission due to electron beam reflection on an aperture part by specifying a clearance between a stamping type punch and a die in process of stamping the aperture part so that a rough cut shape is formed. CONSTITUTION:A clearance between a stamping type punch 4 and a dice 5 in process of stamping an aperture in a shadow mask frame 1 is specified to be 1% to 2% or 25% to 40% of plate thickness. In the case of either clearances, a discrepancy in cracks occurs between the punch 4 side and the die 5 side, and the second shear 6 is generated to form a rough cut shape. Therefore, electron beams are deflected in every direction and so the reflected electron beams are not collected on the side of a fluorescent screen, and fluorescent screen emission sensitive to eyes does not occur.

Title: Control system for inverter of system interconnection photovoltaic power generating plant
Inventor: TOKUDA KENSHO
IPC: G05F1/67
Filed: 1986-11-27
Abstract: PURPOSE:To transmit the electric power generated by a solar battery to the AC side with high efficiency by using a correction circuit containing a nonlinear circuit showing the relation between the maximum DC power value that varies by the solar radiation value of the solar battery and the voltage set at the generated point of said maximum DC power value. CONSTITUTION:The electric power generated by a solar battery 1 is equal to the level of the electric power calculated from the voltage and the current of the DC side in a state where the reactive power zero control is carried out in a system linking sunbeam power generating device. Thus the voltage and the current of the DC side are detected by a voltage detector 8 and a current detector 10 respectively to obtain the electric power generated by the battery 1. This electric power is approximated to the known characteristics of the maximum power generated by the battery 1 by a nonlinear circuit 122. The optimum value of the DC input voltage corresponding to the solar radiation value is always obtained via the circuit 122 and the difference between said optimum voltage value and the detected value of the DC voltage. This difference is supplied to an error amplifier PID13 for control of the output pulse train of an inverter 4. Thus the inverter 4 can always be actuated with high efficiency against the solar radiation value.

Title: Manufacture of cemented mn-zn ferrite
Inventor: TAKAGUCHI KAZUHIRO
IPC: H01F1/34
Filed: 1990-10-23
Abstract: PURPOSE:To manufacture the above material of less cementation failure and no deterioration in magnetic characteristics with high yield by a method wherein cementing temperature and sintering temperature of polycrystalline ferrite satisfy a specific relation. CONSTITUTION:In the case of cementing Mn-Zn ferrite single crystal and polycrystal of the same composition, cementing temperature TB( deg.C) and sintering temperature TS( deg.C) of polycrystalline ferrite are set to satisfy a relation TS<=TB<=S+100. When cementing temperature is lower than sintering temperature, cementation is difficult; reversely when higher, granular growth of polycrystal and growth of single crystal proceed. To reduce sliding noise by a cemented head with this cemented material applied to a magnetic head, it is desired that the size of a crystal grain of the polycrystalline part is 20mum or less. To prevent dispersion in the ratio of single crystal to polycrystal in each magnetic head, it is necessary to suppress the amount of single crystal growth to 50mum or less. When coupling temperature is higher than sintering temperature of polycrystal by 100 deg.C or more, the size of a polycrystalline grain easily exceed 20mum, and the amount of single crystal growth 50mum.

Filed: 1989-11-02
Abstract: PURPOSE: To detect the presence of predetermined time series from input data by generating a trigger signal when the combination of programmed reference is regenerated according to mobile mode. CONSTITUTION: When the combination of reference is present simultaneously on an input channel, a signal of a point A is changed to a predetermined logic state.
